Abstract (en)
[origin: EP0885913A1] A solid polymer electrolyte obtained by blending (1) a polyether copolymer having a main chain, which is derived form ethylene oxide, and a side chain having two oligooxyethylene groups, (2) an electrolyte salt compound, and, if necessary, (3) a plasticizer which is any one of an aprotic organic solvent or a derivative or metal salt of a polyalkylene glycol having a number-average molecular weight of 200 to 5,000 or a metal salt of the derivative, is superior in ionic conductivity and also superior in processability, moldability and mechanical strength to a conventional solid electrolyte. A secondary battery is constructed by using the solid polymer electrolyte in combination with a lithium metal negative electrode and a lithium cobaltate positive electrode.
